ABSTRACT:
A fuser mechanism in an electrophotographic apparatus is disclosed. The fuser mechanism includes a first roller, a second roller, two elastic units, two adjusting devices, and a driving device. The first roller is rotatably and movably disposed in the electrophotographic apparatus. The second roller is rotatably disposed in the electrophotographic apparatus. The second roller is separated from the first roller with a gap for a paper passing through. Two elastic units are respectively disposed on two ends of the first roller to buffer movement of the first roller. The adjusting device is movably disposed between the first roller and the second roller. The drive device drives the adjusting device to push the first roller and adjust the gap.
